By Noah — last updated & pricing verified October 23, 2026.

> **Verdict:** Choose Proton Drive if you are an individual or small team that wants end-to-end encrypted storage with published prices, 5 GB free, 200 GB for $4.99/month, and open-source, audited clients under Swiss jurisdiction. Choose Tresorit if you work in finance, legal, or healthcare and need zero-knowledge storage plus encrypted data rooms, SSO with Azure AD, Okta, or Google, audit logs, and EU-only or regional data residency. The deciding factor is business compliance tooling versus price transparency: Tresorit sells those controls but publishes no plain-number prices and has no free plan.

## Proton Drive vs Tresorit pricing: which costs less?

Proton Drive costs less to start, with a free 5 GB plan and published prices from $4.99/month, while Tresorit has no free plan and does not publish its per-user prices as plain numbers.

Proton Drive Plus is $4.99/month for 200 GB with 10-year version history, Proton Unlimited is $12.99/month for 500 GB plus Mail, VPN, Calendar, and Pass, and Proton Duo is $16.99/month for 2 TB across 2 users, each with a 30-day money-back guarantee. Tresorit sells Professional (1-user minimum, 4 TB), Business (3-user minimum, from 6 TB), Business Pro (5-user minimum, from 15 TB), and custom Enterprise plans after a 14-day free trial. Tresorit's pricing page renders figures through client-side JavaScript and third-party sources disagree on rates, so buyers should request a current quote.

## Is Proton Drive more secure than Tresorit?

Proton Drive and Tresorit offer the same core protection, since both encrypt files on the device so the provider cannot read them; Proton Drive adds open-source, audited clients, while Tresorit adds business controls like SSO, audit logs, and data residency.

Proton Drive's GPL-3.0 client code is public on GitHub and has been independently audited by third-party security firms, and Proton operates under Swiss privacy law. Tresorit's zero-knowledge design means its servers never hold a readable copy or the keys to decrypt one; business tiers add SSO, granular sharing permissions, audit logs, and EU-only or regional storage, and Business Pro adds dynamic watermarks, auto-deletion policies, and SIEM integration. With Proton Drive, a lost password cannot be recovered without a saved recovery kit.

## Which is better for business compliance, Proton Drive or Tresorit?

Tresorit is better for compliance-driven businesses, offering encrypted data rooms, SSO, audit logs, and data residency in the EU or 12 global regions for finance, legal, and healthcare teams.

Tresorit Engage provides encrypted data rooms for due diligence, legal review, and client collaboration with people outside the organization, and the eSign add-on handles encrypted digital signatures, with 16 free eSignatures on Professional. More than 11,000 organizations use Tresorit, and it holds a 4.8/5 rating from 130 Capterra reviews. Proton Drive's published plans center on individuals and small teams, with password-protected, expiring sharing links and Proton Docs and Sheets for collaboration.

## Which is easier to use, Proton Drive or Tresorit?

Proton Drive is easier to use, with a low learning curve against Tresorit's moderate rating, and a free plan that lets anyone start without a trial clock.

Proton Drive works like consumer cloud storage: sync clients for Windows and macOS, apps for iOS and Android, and automatic phone photo backup. Tresorit covers more desktops, adding a Linux sync client, but its encryption-first design adds friction compared with consumer tools like Dropbox or Google Drive for casual use. Tresorit's Business and Business Pro plans also require at least 3 and 5 users, which prices solo users and very small teams out of mid-tier features.

## Strengths and weaknesses

### Proton Drive

- Pro: Files are end-to-end encrypted client-side, so Proton cannot read stored content.
- Pro: Client source code is open source (GPL-3.0) and independently audited.
- Pro: 5 GB free tier is more generous than most end-to-end encrypted competitors.
- Pro: Based in Switzerland, subject to strict Swiss privacy law rather than US or EU data requests.
- Con: Lost passwords can't be recovered by Proton for end-to-end encrypted content without a saved recovery kit.
- Con: Free tier storage (5 GB) is modest compared to Google Drive's 15 GB free tier.
- Con: Best value per dollar requires the pricier Proton Unlimited bundle rather than a Drive-only plan.

### Tresorit

- Pro: Zero-knowledge, end-to-end encryption means Tresorit cannot read customer files even if compelled to.
- Pro: Tresorit Engage provides encrypted data rooms purpose-built for due diligence and client collaboration, not just internal file sync.
- Pro: Data residency choice (EU-only or one of 12 regions) helps meet regional compliance requirements.
- Pro: Native apps across Windows, macOS, Linux, iOS, and Android with desktop sync folders on every major desktop OS.
- Con: No permanent free tier; every plan is a 14-day trial before billing begins.
- Con: Business tier requires a minimum of 3 users and Business Pro requires 5, pricing out solo users and very small teams from mid-tier features.
- Con: Exact pricing is not transparently listed as plain numbers on the site, requiring a trial signup or sales contact to confirm current rates.
- Con: Encryption-first design adds friction compared to consumer tools like Dropbox or Google Drive for casual, non-compliance-driven use.
